Correct later........................ Such a long-distance attack was a test for the Wei cavalry.

What's more, Yunzhong is Tuoba Xianbei's base camp, Tuoba Liwei invaded and merged with the state, and did not bring all the troops, but only mobilized about half of its men and horses, half of them went out to fight, and half stayed behind.

Of course, Tuoba Liwei's move was not to guard against the Wei army, he didn't think that the Wei army would have the ability to attack his lair and leave half of the army, the main reason was to guard against the attacks of other tribes in Xianbei, especially Murong Xianbei in the east, who has always been a strong opponent of Tuoba Xianbei.

The great unification of the Xianbei people has to be traced back to the era of Tanshi Huai, the real king of Xianbei dominated the grassland desert, so that the Xianbei tribes coexist in harmony and are united with the outside world. But the good times didn't last long, after the death of Tanshi Huai, the Xianbei people fell into a state of disintegration again, and the tribes attacked each other and fought endlessly.

Tuoba Liwei was originally only the leader of a small tribe, but through his continuous annexation, he gradually became the most powerful of the Xianbei tribes.

The grassland was originally a place where the weak and the strong ate the strong, natural selection, survival of the fittest, either I destroyed you, or you destroyed me.

Therefore, Tuoba Liwei has always maintained enough troops in the clouds, just to prevent trouble, he doesn't want to go out on the expedition and the old nest is taken away by someone and a tragedy happens.

Cao Liang naturally knew this, so he thought that it would be difficult to sneak attack Yunzhong, but after some thought, Cao Liang also agreed with Huan Fan's point of view, only by ending the nest of the Xianbei people can we truly eliminate the Xianbei people's troubles in the Central Plains.

So Cao Liang was ready to give it a go, and he gathered a cavalry team composed of the Yue Cavalry Battalion, the Tun Cavalry Battalion and the Xiangyong, totaling 20,000 people, and prepared to run long distances into the clouds to burn the things carefully prepared by the Xianbei people for the winter.

Before leaving, Cao Liang handed over the defense of Yanmen Pass to Huan Fan, who had full authority to command and mobilize the troops defending the city, and Yanmen Taishou Le Qi assisted him.

Because Cao Liang knew that if the news of the sneak attack on Yunzhong reached the ears of the Xianbei people who invaded northern Shanxi, the Xianbei people would inevitably be in a mess, and at that time, Yanmen Pass would definitely bear several times the usual attack power, and after he transferred 20,000 troops, it would inevitably seriously affect the defense of Yanmen Pass.

After arranging all this, Cao Liang personally led the cavalry to leave Yanmen Pass.

Originally, Huan Fan asked Deng Ai and Shi Bao to lead the expedition, but Cao Liang thought that this battle was very important and he had to be in command, so Cao Liang was able to override public opinion and personally lead the cavalry army to the battle.

In addition to the 5,000 men and horses of the Yue Cavalry Battalion and the Tun Cavalry Battalion, Cao Liang also brought 10,000 more cavalry with him on this expedition, and these cavalry were from the newly recruited Xiangyong.

Because a lot of war horses were captured from the Huns, no matter how many cavalry were formed, the only thing that restricts the number of cavalry is the number of people who can ride horses.

Fighting with these Hu people, cavalry is the key, only by riding can we really defeat these Hu people, if you rely on infantry alone, even if there are spear formations and partial carriages, at most it can only maintain a draw, if you want to really defeat the Hu people, it is impossible without cavalry.

After leaving, Cao Liang made Deng Ai the vanguard, and changed into the clothes of the Xianbei people, and branded the banner of the Xianbei people, so that it would be convenient to act.

After all, after leaving Yanmen Pass, he is already in the territory of the Xianbei people, Cao Liang doesn't want to expose his whereabouts without rushing to the clouds, change into the clothes of the Xianbei people, and bring a few Hu guides who are familiar with Xianbei dialect, and he can almost get through the customs in the dark.

All the way to Xiaoxing overnight, the Wei army spent about three days, and finally arrived near Yunzhong.

Yunzhong was originally a county in the Han Dynasty, and the Han army built a city here, but after a long time, the city was eroded by wind and sand, and there were only a few broken wall ruins.

After Tuoba Liwei moved the Tuoba Department here, he did not build the city or repair it, and let the city go down. The Xianbei lived in the felt tents that were more common among the grassland peoples.

This kind of tent is not bad in terms of warmth, and it is also easy to disassemble and move, and it is a necessary means of life for Xianbei people.

Because there is no constraint of the city, most of the Xianbei people's living places are relatively loose, classified by tribes and clans, each family has its own territory, looking at it from a distance, you can see a large number of tents, the scene is extremely spectacular.

There are no walls or fences in the whole station, and there will be some fences in the small tent group, which should be a group of a certain clan.

Before launching the attack, Cao Liang deliberately let the Wei cavalry hide and sent scouts to find out the situation of the Xianbei people's garrison in detail, especially the Xianbei people's forage field.

The goal of the forage field was very large, but the scout quickly found it, just northeast of Yunzhong, about five miles away from the Xianbei people's residence.

Because the forage field is very important to the Xianbei people, so around the forage field, a lot of troops are stationed to surround the forage field, if Cao Liang wants to attack the forage field, he must clean up the surrounding army.

After receiving the return of the scout, Cao Liang had a general understanding of the terrain here, but now in broad daylight, it is not very advantageous to launch an attack, and it is easy to be besieged by the Xianbei people after being exposed.

Therefore, Cao Liang set the time of the attack at midnight three watches, and most of the Wei army entered the land of sleep during this time period, which was the best opportunity for the Wei army to sneak attack.

Cao Liang divided the cavalry into three parts, the Yue cavalry battalion and the tun cavalry battalion were each part of the cavalry, and the Xiangyong cavalry was part of it, and after the operation began, Deng Ai and Shi Bao were responsible for launching an attack in the clouds, setting fire to the Xianbei camp to attract the attention of the army guarding the forage camp, and Cao Liang launched an attack on the forage field from the other side.

At midnight, Deng Ai and Shi Bao respectively led the Yue cavalry battalion and the Tun cavalry battalion, one from west to east and the other from south to north, and at the same time broke into the Xianbei camp.

Their first task was to set fire to cause chaos, which was not a difficult task for the two of them, these tents were flammable, and the Wei army rushed to the front and threw a few torches to ignite a raging fire.

Soon, this piece of the cloud fell into a sea of fire.
